【摘要】 滑石的增强改性作用源自其片状结构,主要用于汽车和家电行业使用的聚丙烯塑料增强改性。滑石的纯度、白度、细度和片度"四度"是决定改性效果的主要因素。提高产品的细度和径厚比均可提升效果。气流磨在微细研磨和提高径厚比方面几乎已经发挥到了极致,而采用砂磨不但能进一步提高细度,还能更好地保持滑石的片状结构和径厚比,显著提升制品的各项性能,是今后高性能滑石粉体的发展方向。更多还原

【Abstract】 The remarkable lamellar feature enables talc significantly reinforces physical performances of polymers, especially polypropylene widely used in automobile and household appliance sectors. The efficiency of reinforcement mainly depends on talc’s 4 dimensions: purity, whiteness, fineness, and lamellar structure. The jet mill has reached its limit to improve fineness and aspect ratio. Sand mill, can not only improve talc fineness but also maintain its lamellar structure with high aspect ratio, improving product’s various performance. Sand mill grinding is the future development trend for producing high-performance talc.更多还原
